Jean's bedroom is 11 feet by 11 feet. She has chosen a carpet which costs $28.80 per square yard. This includes installation.

Determine her cost to carpet her room

To determine the cost to carpet Jean's bedroom, we need to follow these steps:

1. **Calculate the area of the bedroom in square feet:**

   The bedroom is 11 feet by 11 feet, so:
   \[
   \text{Area in square feet} = 11 \times 11 = 121 \text{ square feet}
   \]

2. **Convert the area from square feet to square yards:**

   Since there are 9 square feet in a square yard, we convert the area:
   \[
   \text{Area in square yards} = \frac{121 \text{ square feet}}{9} \approx 13.44 \text{ square yards}
   \]

3. **Calculate the total cost:**

   The cost per square yard is $28.80. So, the total cost is:
   \[
   \text{Total cost} = 13.44 \times 28.80 \approx 387.07
   \]

Therefore, the total cost to carpet Jean's room is approximately **$387.07**.
